I found an excellent version of "Tachash" on Wikipedia at http://en.wikipedia.org/w/index.php?title=Tachash&oldid=462519055 . The references seem to be very good, as far as I could determine. Is this version of the article useful and reliable?
The idea that Wikipedia is unreliable is not completely sound. It's good for you to verify the information, but incorrect information on Wikipedia is more than likely going to be corrected by another user. That's actually the beauty of Wikipedia. It's more fact-checked than many other individually created sources.
For the most part I can agree with your assessment of Wikipedia. However, the version of the article "Tahash" currently featured here on eNotes has been characterized by one of their editors as a "crap version" this date (see the talk-page of the article under "Redirect"). The version recommended on the talk page by "just a bystander" is at http://en.wikipedia.org/w/index.php?title=Tachash&oldid=462519055 and is in my opinion superior to the one I had edited Nov. 2010. Several individuals have repeatedly attempted to provide correct information from actually reliable sources; however, not only have those sources been rejected, the individuals providing them have been charged with "sock-puppetry" and have been blocked from contributing to Wikipedia.
